Title: Pwm output controlling circuit
Inventor: SUEZAWA TAKAAKI
IPC: H03K7/08
Filed: 1997-07-28
Abstract: PROBLEM TO BE SOLVED: To realize an output controlling circuit, which can increase an output accuracy and simultaneously and individually control a plurality of outputs, and which has a simple circuit configuration, thereby minimizing the factors which cause current consumption and noise. SOLUTION: This circuit is provided with a counter 10 which can always operate by itself. In response to a counted value of the counter 10, the cycle and duty of a PWM output signal based on a cycle set value and a duty set value are simultaneously controlled, thereby controlling the cycle and duty once in one cycle of the counter 10. By this method, an output accuracy can be increased and the PWM output signals are individually and simultaneously controlled. Since the PWM output signals are outputted, with the cycle and duty being independently controlled, a circuit configuration can be simplified and the factors which causes current consumption and noise can be suppressed.

Title: Solar battery
Inventor: TAKESHIMA MASUMI
IPC: H01L31/0687
Filed: 1982-11-20
Abstract: PURPOSE:To obtain high output voltage and high conversion efficiency of a solar battery by laminating in series connection a plurality of p-n junctions, and reducing the value of mixed crystal (x) of Ga1-xAlxAs from the photoreceiving surface into the interior as x1>x2>...>xn. CONSTITUTION:The reduction of mixed crystal ratio may be discontinuous at every p type layer and n type layer, or discontinuous at every p-n junction unit or entirely continuous. At this time forbidden band width is maximum on the photoreceiving surface, is decreased toward the interior, and the light is absorbed in longer wavelength in deeper interior. When the slope of x and the thickness of the thickness of each layer are suitably thinly selected, the production of electron and hole pairs and the subsequent isolation thereof all occur at the p-n junctions, the output voltage becomes the sum of the generated light voltages of the respective junctions, to become large value. The impurity density is better when it is higher due to reduction in the series resistance, the suppression of photoelectric conversion loss is better when lower, and a range of 5X 10<17>-10<19>cm<-3> is adequate. The length of the p-n junction unit is advantageous when selected to 0.5/N-4/Num in case that the number of the junctions is N.
